Grandes Misiones de Exploración del Sistema Solar
Overview 1 – Magnetism is everywhere in the universe. Examples 2 – The adventure to measure the magnetic field in Space 3 – Space magnetic fields measurement. Desire versus Practical reasons 4 – Magnetic Cleanliness Concept 5 – Types of magnetic measurements 6 – The approach of miniaturized compact magnetometers Magnetism is everywhere The Magnetic Field of the Earth Shields the planet protecting life on Earth “Relatively close” magnetic fields Field of the Sun Planetary Fields The Earth Jupiter Saturn Uranus Neptune Other magnetic fields If it were for magnetic fields to be measured in Space… every space mission should have magnetometers on board Magnetic Sensors for Space? And beyond Venus Mercury The Earth Mars Ceres Jupiter Saturn Uranus Neptune Pluto, Eris Makemake, Haumea Once we are there we cannot expect any help Are there magnetic sensors capable to accomplish the technical requirements with enough robustness? The heritage of the military sensors (Technology Readiness Level-TRL) AEROSPACE MILITARY INDUSTRIAL COMMERCIAL What is the subject of Space Magnetometry about? Magnetic Cleanliness…a headache Every vehicle has a magnetic signature NANOSAT-01 OPTOS Magnetic Signature attenuates very fast with distance ~1/r3 14 1 3 1960 VOYAGER PIONEER 10 / 11 MCP are difficult to implement and very expensive! 1980 Fecha (años) 2000 3 m de pértiga dedicada BEPI PLM - Limitado COLOMBO 4 m de pértiga compartida SOLAR ORBITER PLM - Limitado ¿¿¿???
